IMPROVEMENT IN MACHINES FOR MEASURING CLOTH.

To all whom it Wmy concern:

Be it known that I, CHARLES M. SwANY, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and ImprovedMachine for Measuring Cloth; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the accompanying drawings, making a part of this specification, inwhich Figure 1 is a plan or top view of my invention Fig. 2, alongitudinal vertical section of the same, taken in the linear 00, Fig.1 Fig. 3, a section, taken in the line, y 9 Fig. 1.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in the employment or use of a drum provided witha screw-shaft and nut, and also with a ratchet, in connection with apressure-roller, lever, and a graduated plate, all being arranged insuch a manner and in such relation with two drums or shafts, from one ofwhich the cloth is unwound and upon the other of which it is wound, thatthe desired work may be done in an expeditious and accurate manner.

A represents a rectangular box, at about the center of which there isplaced transversely a drum, B, the shaft 0 of which works in fixedbearings. This shaft 0 projects a considerable distance beyond one endof the drum B, and it has a screw, a, cut upon it, on which a nut, 1),is fitted, the ends of said nut resting on two parallel guide-plates, bb, which are attached to supports 0 0, the latter projectinghorizontally from the inner side of the box A. One or both of theseplates 1) I) are graduated into degreesindicatin through the medium ofthe nut D the number of revolutions of the drum, and the fractionalparts of a revolution. It is designed to have the drum B a yard incircumference. Directly below the drum B there is a roller, E, the shaftF of which has its bearings in slides G G, which are fitted or work onvertical guides (l d, attachedto the surfaces of the sides of the box A.Underneath each slide G there is placed a spring, H, and these springshave a tendency to keep the roller E pressed upward against the drum B,as will be understood by referring to Fig.

2. On the end of the drum B, from which the screw portion of the shaft Oprojects, there is fitted a racthet or milled-wheel, I, underneath whichthere is a lever or pawl, J, which is connected to one of the supports,0. This lever rests on the roller E, and said lever or pawl is madeconcave both at its upper and lower edges, to suit respectively theratchetl and roller E.

The operation is as follows: be measured (shown in red) is placed on areel or shaft at either end of the box A, and the cloth is passedbetween the drum B and the roller E, and is wound upon a reel or shaftat the opposite end of the box A, motion being communicated between thetwo reels by a belt. The drum B is rotated by any convenient power, andthe cloth thereby moved below it, and the revolutions of the drum B arerecorded by the nut D on the graduate plates 1) b. When the cloth isbetween the drum B and roller E, the lever J is free from the ratchet ormilled wheel I, but as soon as the cloth has passed from between themthe springs H force up the roller E in contact with the drum B, and thelever J, in consequence of resting on the roller E, is brought incontact with the ratchet or milled wheel I, and the rotation of the drumB instantly stopped, so that the exact measurement of the cloth will beobtained.

The whole arrangement is exceedingly. simple, may be manufactured at asmall cost, and will perform itswork or measure the cloth accurately.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The drum B, provided with the screw-shaft O and nut 1), in combinationwith the graduated plates 1) I), one or both, pressure-roller E, and thelever or pawl J, and ratchet or milled wheel I, or their equivalents,all arranged to operate substantially as and for the purpose herein setforth.
